📍 Geographic Location of Mattsee
Geographic Overview
Austria's country calling code +43 is followed by a National Destination Code (NDC) that identifies a specific geographic area. The NDC 6217 is assigned to the Mattsee region, located in the state of Salzburg (Salzburger Land). Mattsee is a picturesque town situated on the shores of Lake Mattsee, approximately 20 kilometers north of the city of Salzburg. The area code 6217 covers Mattsee itself and the immediate surrounding communities, including parts of the Flachgau district.
Dialing Formats
For callers within Austria, the national trunk prefix 0 must be dialed before the area code. Thus, a local number in Mattsee is dialed as:
- 0 6217 XXXXX (national format)
For international callers, the Austrian country code +43 replaces the leading zero. The international format is:
- +43 6217 XXXXX (international format)
Here, XXXXX represents the subscriber's local number, which typically consists of 5 to 7 digits. The total length of a complete international number (including country code but excluding the trunk prefix) is 9 to 11 digits.
Caller Instructions
Local callers within the Mattsee area may be able to dial the subscriber number without the area code if they are within the same local calling area, but this is not always guaranteed due to overlay and number portability. For clarity, it is recommended to always use the full national format.
Callers from other Austrian regions must dial 0 6217 followed by the local number.
International callers should replace the leading zero with the +43 country code. For example, to call a Mattsee number 12345 from abroad, dial +43 6217 12345.
Regulatory and Technical Notes
Austria's numbering plan is regulated by the Rundfunk und Telekom Regulierungs-GmbH (RTR). Geographic area codes like 6217 are assigned to fixed-line services, but due to number portability, a number with this prefix may be routed to a VoIP or mobile service. However, the tariff structure often remains based on the geographic origin. When dialing from a mobile phone, it is advisable to include the area code even when calling within the same region to ensure proper routing.
As of recent years, Austria has not introduced overlay codes for this area, so the 6217 prefix remains unique to the Mattsee region. However, always verify the current dialing procedures with your service provider, especially for business-critical communications.
